[quote=briansd1]The use of services by ethnic group is pretty-well documented. People who work in social services would tell you that Vietnamese-Americans comprise a large portion of clients.

Here’s one report.

• The poverty rate for Vietnamese individuals and families is much higher than other race/ethnic groups; in 2008,
the poverty rate for Vietnamese people was 14.7%. The poverty rate for all individuals in Orange County was
9.9%.

If I get some time, I’ll find you some more recent information.

Unfortunately, the academic studies tend to lag by a decade or two are more data is available and academics take interest in studying the populations.

From Frum Forum, here’s an interesting article on Vietnamese voting for republicans.

Thankfully, as Vietnamese-Americans become more integrated, they vote more independently from their refugee parents.

You do realize a good portion of these immigrants are borderline welfare fraudsters…IE: kinda hard to substantiate overseas assets and income in the U.S. Just saying…..The sad part is some folks get better medical on Medicaid then folks on Medicare.
